How do I get my ARC 500 software to install my freqs into a different scan list? It always goes to sl 1 and overwrites all other entry's. I tried checking box sl 2 to upload but it still goes into sl 1. Also how can I add other freqs to a sl without deleting the entire list which has happened every time I tried to put in a new freq. Does it have to be selected in the global menu on the scanner first, or can I select it from the software? Thanks for any help. Using the GRE 500.
